Hair Follicle Drug Testing - Overlea, MD

What it is, How it works

Hair analysis has emerged as an effective mechanism for identifying substance use through its ability to capture drug and alcohol indicators over time. The hair's structure retains traces of alcohol and drug markers as it grows, allowing for a retrospective analysis. When extracted from near the head, hair can reveal substance usage history spanning up to three months. The collection process is straightforward, with less susceptibility to tampering, and transportation is uncomplicated.

A 1.5-inch section comprising roughly 200 hair strands (similar in size to a #2 pencil) closest to the head scalp provides 100mg of hair, serving as the optimum sample for both preliminary and confirmatory phases. For EtG, additional tests, or analysis involving more than 10 panels, a specimen of 150mg is advisable. It is suggested to measure the sample weight using a jeweler's scale. In cases where scalp hair is inaccessible, a comparable quantity of body hair is acceptable. 'Head hair' refers specifically to hair on the scalp, while 'body hair' includes all other hair types such as facial and axillary hair.

Process Overview

The laboratory procedure of testing drug results encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the initial incorporation of a sample into a laboratory's system; this phase checks that the sample was appropriately sealed and delivered, assigns it a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent in an electronic chain of custody system.

Screening conducts a preliminary swift assessment for substances of abuse. While Screening provides a cost-efficient approach to dismiss drug usage in many instances, any positive results discovered necessitate a follow-up for legal validation. Specimens with presumptive positive results in Screening require further confirmation.

Upon identifying a presumptive positive in the Screening phase, additional hair is extracted from the existing sample and prepared for the Extraction phase. At this point, drugs are drawn from the hair at concentrations lower than those typical in other testing methods (e.g., urine or saliva), rendering hair drug testing the most challenging method to execute.

Verification of any positive screen is achieved using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Presumptive positive samples undergo a washing process when necessary before confirmation occurs. The entire laboratory procedure from Accessioning through Confirmation undergoes review in accordance with both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug intake for up to 90 days, surpassing the shorter detection window of urine tests.
• Cheating challenges: Due to the difficulty in manipulating a hair drug test, the results obtained are more reliable.
• Historical data provision: It provides insight into patterns of drug consumption over time, not solely immediate usage.

Limitations:

• Inability to identify recent usage: Drugs only become detectable in hair after about 5-7 days.
• Expense: Hair drug tests typically incur higher costs than alternative drug testing approaches.
• Result variations: Certain aspects such as hair color and individual hair growth variation can impact drug metabolite concentrations in hair.

Note: Although commonly labeled as "hair follicle tests", the evaluation focuses on the hair strand itself rather than the follicle beneath the scalp.
